Thinking is this exercise..we need to compare and analyse examples of virtual and physical toys.
And I remember on the real dolls that everyone had play when we were children. Go to walk with a trolley and the doll inside, prepare unreal food for them, change their clothes... Really fun.

And now you can do all of that things inside one screen. For example with the famous game: Pou.

But it was soo many years ago, when tablets or smartphones were unimaginable, when "Tamagochi" came to ours lifes. I remember all my class at the school with a tamagochi in their pockets giving to them food (digital food).
